- * output, protocol traces and testing).
- *
- * Support for loading mixer volume and mux configuration from the
- * interface during driver initialisation added in May 2021 (thanks to
- * Vladimir Sadovnikov for figuring out how).
- *
- * Support for Solo/2i2 Gen 3 added in May 2021 (thanks to Alexander
- * Vorona for 2i2 protocol traces).
- *
- * Support for phantom power, direct monitoring, speaker switching,

- * - gain/volume/mute controls
- * - level meters
- * - line/inst level, pad, and air controls
- * - phantom power, direct monitor, speaker switching, and talkback
